DW-100 single specimen low-temperature brittleness testing machine

1、 Purpose:

DW-100The single sample method rubber low-temperature brittleness testing machine is used to determine the highest temperature at which the vulcanized rubber sample fails under specified conditions due to impact, which is the brittleness temperature; It is possible to conduct comparative identification of the performance of rubber and other elastic materials under low temperature conditions, and to determine the brittleness temperature and low-temperature performance of different rubber materials or different formulations of vulcanized rubber. Therefore, in terms of quality inspection of scientific research materials and their products, as well as control of production processes, they are all excellent. This instrument is based onGB/T1682-2014A compressor refrigeration equipment designed according to national standards and carefully developed. This equipment adopts a cascade imported compressor refrigeration technology, utilizing the principle of thermal equilibrium and circulating stirring to achieve automatic uniform cooling and constant temperature of the sample.
